Title
(EN) ELECTRICAL POWER ASSISTANCE DEVICE FOR TRANSPORT WHEELCHAIR
(FR) DISPOSITIF D'ASSISTANCE ÉLECTRIQUE POUR FAUTEUIL ROULANT DE TRANSPORT
Abstract
(EN)
An electrical power assistance device designed to be removably coupled to existing transport wheelchairs to provide electric power to aid in transportation of a person sitting in the wheelchair, while being detachable to allow the transport chair to fold up for easy storage in a car or other vehicle. The electrical power assistance device includes a motor powered by a rechargeable battery, where the motor drives an internal shaft which rotates a pair of friction wheels. A clutch, provided on a separate axle coupled to the friction wheels by eccentric disks, allows the friction wheels to engage or disengage with the rear wheels of the transport wheelchair.
(FR)
L'invention concerne un dispositif d'assistance électrique conçu pour être accouplé de manière amovible à des fauteuils roulants de transport existants pour fournir de l'énergie électrique en vue d'aider au transport d'une personne assise dans le fauteuil roulant, tout en étant détachable pour permettre le repliage du fauteuil de transport pour un stockage facile dans une voiture ou un autre véhicule. Le dispositif d'assistance électrique comprend un moteur alimenté par une batterie rechargeable, le moteur entraînant un arbre interne qui fait tourner une paire de galets de friction. Un embrayage, situé sur un essieu séparé accouplé aux galets de friction par des disques excentriques, permet aux galets de friction de venir en prise avec les roues arrière du fauteuil roulant de transport ou de se désolidariser de celles-ci.
